Title: Integrated type air conditioner
Inventor: KISHITA KOUJI
IPC: F24F1/02
Filed: 1982-07-22
Abstract: PURPOSE:To constitute an integrated type air conditioner having a cooling and dehumidifying functions in a simplified structure, by arranging such that a heat exchanger is provided at the downstream of evaporator and condenser, and an air stream may be controlled by switching to enter or not to enter into the heat exchanger after passed through the evaporator and the condenser. CONSTITUTION:Dampers 8 and 9 of condenser 3 and those 10 and 11 of evaporator 4 are positioned as shown in the drawing. This arrangement can permit the air stream to inject into a room or to the outside from the condenser 3 and the evaporator 4 without detouring a heat exchanger 7 at all. By operating dampers 8 to 11 to move to respective positions illustrated, the air stream in the condenser 3 and the evaporator 4 are introduced into a heat exchanger 7 wherein a heat exchanging takes place therebetween, and thus the air cooled in the evaporator 4 is dehumidified. In this manner, by switching the dampers, either cooling or dehumidifying operations can be selected with a resultant simplified construction.

Title: Detector for phase difference between picture component signals
Inventor: KUMADA JUNJI
IPC: H04N19/50
Filed: 1986-06-04
Abstract: PURPOSE:To correct a phase difference while detecting the phase difference between picture component signals during the operation of a color camera or a color receiver by obtaining a shift giving the peak value of a correlation function. CONSTITUTION:Each signal smaple stored in memories 9, 10 is read consecutively, led to a correlator 11, where the correlation coefficient between two-picture component signals is calculated. In this case, the read phase of a measured signal f(x) from the memory 10 is shifted sequentially to the read phase of a reference signal g(x) from the memory 9 to obtain a correlation coefficient corresponding to each shift, that is, the discrete value of the correlation function, that is, a sample value is obtained. Then the discrete correlation function obtained in this way is led to an interpolation device 12, where interpolation is applied, the result is led to a peak detector 123 to obtain the quantity of shift giving the peak of the function. Thus, the phase difference between picture component signals is detected in nearly real time as the peak position shift of the correlation function.

Inventor: MISAWA TOSHIYUKI
IPC: H04L27/156
Filed: 1981-08-17
Abstract: PURPOSE:To reduce required number of filters of SCF, by changing over a clock and the capacity value of a capacitor. CONSTITUTION:A received signal is inputted into an SCF19 through a high-pass filter composed of a microphone 15, a condenser 17, and a resistance 17, and an amplifier 18. Since a clock frequency is stepwise overlapped on the output of the SCF, the offset due to the operational amplifier of the SCF is removed by a buffer 22, a condenser 23, and a resistance 24 after the output is passed through a low-pass filter composed of a resistance 20 and a condenser 21. A demodulating circuit 28 measures the cycle of square waves which are the output of a  comparator 27 whether it is a mark or a space, and obtains digital signals. The clock of the SCF is obtained by an oscillation dividing circuit 30 having two dividing ratios and a quartz resonator 29, and, by inputting the dividing ratio, B/C, dividing frequencies appropriate to the two frequency standards are given.

Title: Bearing unit for universal joint
Inventor: MAKASE KEIICHIROU
IPC: F16C21/00
Filed: 1987-05-26
Abstract: PURPOSE:To make it possible to prevent a load concentration to one point by making a clearance between a trunnion and a roller the larger as the closer to the tip of the trunnion, and making the contact of the trunnion uniform by the inclination of the axis of the trunnion. CONSTITUTION:The clearance between the peripheral surface of a trunnion 31 and the peripheral surface of a roller 43 is set the larger as the closer to the tip of the trunnion 31 by the difference between the crownings 80 and 90. As a result, an inclination of the trunnion 31 and the bearing case responding to the minimum clearance cannot be avoided. However, when the trunnion 31 is inclined, the whole peripheral surface of the roller 43 and the peripheral surface of the trunnion 31 are contacted completely. The concentration of load to the tip side of the trunnion 31 can be prevented consequently.
